Blender, Unity and texturing multiple objects.

[SiliconPyro]

I have a part in Blender that is composed of three separate objects. It exports to Unity just fine. When I applied a material in Unity though, it put the same material on all three objects. Should I export the parts separately from Blender, then combine them in Unity? Is there a method I'm overlooking? I really want separate textures for each mesh.

think of it in terms of KSP shaders. KSP only allows 1 shader on a mesh object. combine non-moving mesh objects that share the same shader in KSP; then moving parts that share same shader; then parts that require different shader and/or move independently.

to use your VTOL engine as example; the nozzles can be one object (they move), and engine body is one object; Even though they might share the same shader, Emissive/Diffuse/Specular for instance. If the nozzles were fixed, then you could combine everything into a single object and apply a single KSP shader. if you have nozzle on one side, and a teletubbie on the other side, and they are moved by different animations, then you'd have 3 mesh objects, with 1, 2, or 3 KSP shaders.

Okay, got it. That makes sense.

Okay, I'm not getting it. I have separate objects in the scene, but every time I switch the material on one, it changes on the others.

because they are sharing the same shader (KSP name); or material (Unity name).

if you want Part A to have say... Diffuse/Specular, and Part B to have Bumped/Specular; even though they use the same diffuse texture. you need to create 2 materials, assign each the same diffuse; and a normal map for the Bumped/Specular shader.

Okay, I figured out what was happening. Unity was importing textures by default. I un-checked that option, then just dragged the materials onto the models in the scene view and now they're working perfectly.
